Democratizing Ideas: Submit Proposal for Your Own Freedom Chip!

Submit proposals at https://info.sifive.com/democratizing-ideas before Oct 31, 2018!

• Do you have a great idea for

a chip? Do you have an IP

block, such as an

accelerator, a co-processor?

• We are considering projects

for SiFive partnership which

could involve access to

custom CPU IP, design

support, and even help

delivering working samples

of your chip!

• Partners to be announced at

First Annual RISC-V Summit,

to be held Dec 3-5, 2018
